Turn on visual effects in Music on Mac
Use the visualiser to watch colourful light shows. You can use the visualiser with or without music; the effects change based on the type of music and whether it’s playing or paused.
In the Music app on your Mac, do any of the following to play music:
Note: A song needs to be playing before you can use the visualizer.
Do one of the following:
Turn on visual effects: Choose Window > Visualiser.
To change visualizer options, choose Window > Visualizer Settings > [option]. For example, to show or hide music videos, choose Window > Visualizer Settings > Play Videos. A tick means that videos will play. (Not all visualizers support options, so Options may be dimmed.)
Tip: To show or hide a list of commands you can use to control the visualiser, press the Question Mark key (?) on your keyboard while the visualiser is on.
Turn off visual effects: Choose Window > Visualiser (to remove the tick), or press the Esc key.
